Independent read-only review of 8a47d30/bbbff77/16c46a5 per
handoff/claude-master-handoff.md's review-and-freeze step. Verified
build/test/lint independently rather than trusting recorded evidence.
Fixed P2: requireSuccess() collapsed HTTP 409/422 into the generic
InvalidResponse, which would have blocked TASK-007's planned
conflict/unprocessable error states. Added ApiFailure.Conflict and
ApiFailure.Unprocessable with test coverage.
Recorded a P3 (CPU-bound work on the Main dispatcher in
CodeBrowserViewModel) for TASK-016 rather than fixing it now. Closed
TASK-005/006's mutual contract-freeze checkboxes. No P0/P1 found.
